GAS-MACHINE.

SPECIFICATION forming part'of `Letters Patent No. 288,752, datedNovember 0,1883. Application inea August es. lees. (No model.)

To a/ZZ whom, zit` may concern: i

Be it known that I, Josnrn S. WOOD, of Brooklyn, in the county of Kingsand State of New York, have invented certain new and useful Improvementsin Gas Machines, of which the following is a specication.

This invention has reference to an improved machine for making gas fromnaphtha or oth er light hydrocarbon oil by means of heat, and it isdesigned especially with a view to furnish a cheap and simple apparatusfor steamboats, railroad cars, and other purposes where a small numberof burners is to be supplied; `and the invention consists of agenerating-retort which is heated by a vapor-burner and supported byoil-supply and gas-conducting pipes at opposite sides .of the burner.The gas-conducting pipeis connected to a mixing-chamber, which isprovided with a"needlevalve and an adjustable inj eetiOn-throat, as willmore fully appear hereinafter, and nally be point- 5o or diminished,according to the quantity of gas ed out in the claim.

Inthe accompanying drawings, Figure l represents a vertical longitudinalsection of my improved gas-machine, and Fig. 2 showsl the arrangement ofthe oil-tank below the body of a car.

y Similar letters of reference indicate corresponding parts.

A in the drawings represents a hollow supporting-stand, to which theoil-supply pipe B is connected. The oil is supplied under pressurethrough the hollow stand A `to a generat-V ing-retort, C,which issupported by pipes E E', which communicate with openings a c in the endsof the retort. The pipe E communicates with the hollow standard, andsupplies the oil to the retort C. rfhe pipe E' conducts the va` pors"generated in the retort to a burner, D, and to a mixing-chamber, F, by aconnectingpipe, E2. The burner D is interposed between 4the hollowstandardA and the pipe El, and

connected with the latter by a small supplyorifice.

The burner D is provided with a needlevalve, D', the tapering end ofwhich serving to open or close the tapering gas-supply oriice e' of thevalve-chamber D2, so that the heating-flame of the burner may beenlarged to be generated. g

The burner D is provided in the usual manner with an air-port, e2, tosupply the quantity of atmospheric air that is required for thecombustion of the vapors.

The mixing-chamber F is provided with a needle-valve, G, andvalve-chamber G', the needle-valve being adjusted in the usual manner ina stuffing-box of the chamber G', so as to open. or close the taperingorifice that leads into the mixing-chamber F.

rlhe mixing-chamber F is provided with an air-port, t', and with aninjection-throat, F', that is connected to the gas-supply pipe whichleads to the burners.

The mixing-chamber can be enlarged or diminished in size by adjustingits inclosingtube up or down on the threaded end of the valve-chamberG', so that the proper proportion of atmospheric air issupplied to andmixed with the vapors in the mixing-chamber, whereby the lights areprevented from smoking. i

In case the gas-1nachine is used in arailroadcar, an oil-tank,H, isstored beneath thebottom of the car, and them achine arranged insuitable position in the gentlemens wash-room. The oil-supply pipe Hofthe tank is provided with a valve having a weighted lever, H2, asshown inFig. 2, so that in case of accident and upsetting of the car thevalve will be automatically closed, and thereby thesupply of oil to thegasmachine automatically interrupted.

The gas-machine is started in the same manner as other gas-machineshaving generatingretorts heated by a burner by lighting alcohol in a cupor dish below the burner. This heats up the oil in the adjoiningoil-supply pipe at one siderof the burner, and supplies vapor to theburner, which then heats the retort.

As `soon as the generating-retort is sufficiently heated, the oil in thesame is changed into vapors, which are then supplied to the burner andto the mixing-chamber, `the needle and injection-throat of which areproperly adjusted, according to the quantity of gas required to theburners. i

The gas-machine thus obtained is of eXtreme simplicity, and can befurnished at very low rates, so that it is specially adapted forsteamboats, railroad cars, and other purposes in which a` smaller numberof burners has to be supplied. The heating-flame of the retort may alsoserve as an illuminating-dame for a room IOO in Which the gas-machine islocated. By closing the needle-valve of the burner the operation of theapparatus is instantly interrupted, While .by the needle-valve and theadjustable injection-throat of the mixing chamber the proper functioningof the sameis fully controlled.

Having thus described my invention, I claim as new and desire to secureby Letters PatentrIhe combination of a generating-retort, C, supportedby upright pipes E E, a heatingburner, D, located between said pipes andconnecting to the gas-conducting pipe E', an oil- Supply pipe, B,communicating with the pipe E, a conducting gas-pipe, E2, and a mixing-15 chamber, F, having a needle-valve, G, and adjustable injection-throatF', substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence 2o of two subscribing Witnesses.
